When I used to race my A12 Runner in the early 70's, it had over 13:1, big valves, a .626 lift cam, 4.88's, etc. I tried switching to an Edelbrock TM7 Tarantula intake, a 2" spacer and a Holley 850 DP for a while. It ran the same times and speed but did not get the hole shot my 6BBLs got...and just didn't have the same wow factor to me.

haven't tried these yet but should be a simple, easy to tune alternative to a 6bbl.
Edelbrock 2x4 setup is less expensive than a 6 pack.
Yeah but it comes w/ 2 edelbrock carbs

Too late gave mine to a chebbie guy.
Decided to try one years ago, bought a shiny new 1407 Edelbrock carb for my 440 4 speed Challenger replacing the strong running (but a little dirty looking) Holley 750dp carb it had on it.
The Edlbrock had a terrible stumble off idle and no where near the performance of the Holley. 
Bought the Edelbrock tuning kit and spent hours trying to tune it.
Called Edelbrock tech line countless times, They had me doing all kinds of stuff including drilling out emulsion tubes, some improvement but the stumble never went completely away and still no where near the performance of the Holley. 
The techs at Edelbrock were nice and helpful and even sent me parts to try for free but in the end they finally admitted these type carbs where NOT designed for performance big block Mopars...more for stock small block chebbies.
Pulled the Edelbrock carb (gave to a chebbie buddy) and replaced with the old Holley and the car ran perfect(and fast) again.
Still got the Edelbrock tuning kit somewhere.
Live and learn.

That is a ridiculous statement from the Edelbrock employee as a carburetor doesn't have a clue as to what is pulling a vacuum under it. Something was wrong with your carb, pure and simple.
I could give you a ride in my GTX as it will explosively break the tires loose by merely stabbing the gas pedal.
With either the 750 AFB (now on my Duster) I use to run, or the 900 CFM Thermoquad that is currently on it.
A great book to read about how Carters work-

 Here's my take. If you want the ultimate "Wow" factor yank the 408 and drop in a GenII Hemi. Done! IMO it's hard to beat an STR12 for a small block in terms of under hood glamor (EXPENSIVE!), but they can be a trial to find, install, and tune properly. If you want the car to perform to it's limit you'll likely find the best way to get there is a single 4 barrel. For vintage look I'd go with a Thermo-Quad, you don't need a Comp series unit either (they work great but are not very street friendly). For a more modern approach it's hard to beat a Holley 950 on a stroker small block with an aggressive cam profile. Six packs are great dependable power makers as well (and if properly tuned) will perform with nearly anything, but it's a lot of extra expense and hardware to get to the same goal a 4 barrel can reach, plus, if you run a stock oval air cleaner a 4 barrel looks basically the same as a Six Barrel when all covered up, all that money and now it's all hidden, that goes double if you run a Shaker hood. Dual 4's are sort of the same story, not really needed but if you like the look and don't mind the added expense you won't likely lose (unless you over carb the engine) or gain any performance over a well chosen single 4 setup.

Are paper 6 pack filters being reproed again or are nos ones still listing for 350 bucks?
If you are talking about the orange round hole original style, no, not to my knowledge, athough they likely will make more eventually. And BTW, the $350.00 examples you commonly see offered are not typically NOS, they are remaining Fram reproductions, NOS (New OLD Stock from the early 70's) usually go for more than that.

...and K&N has a nice filter that will outlast all of us.
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's
1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

The mechanical six pack Holley 2300 carbs were sold over the counter under the Direct Connection banner as "Racing" carbs. They were also used on Ford's during the '60's. It takes a bit of searching, but there are still a lot of nice sets out there, especially if you Google Ford set-ups.
Those carbs were 500 cc 2 bbl's with accelerator pumps. That is all I ran on 6pk setup in the late 70's and early 80's.
How do you make the Ford carbs fit a Mopar manifold? 
the mechanical end carbs were the same size throttle bores and venturi as the factory vacuums, definitely not the 500cfm aftermarket carbs. the ford carbs will bolt up but they were very small, like the mopar and chevy center carbs.

Actually since the Ford carbs all have metering blocks the rear carb won't fit... The center carb always has a metering block so that's not an issue & the front carb just protrudes an extra 3/4" but the rear carb will not fit....
the ford carbs will bolt up because they use side pivot bowls; the same as 6-pak mechanicals.
